 {{{
 :info:configure Creating qmake...
 :info:configure Failed to resolve SDK path for 'macosx10.13'
 }}}

 This error has been encountered several times before, and maybe it was
 thought to be finally resolved; I am not aware which ticket discusses the
 most recent work for it. The issue could be one that does not affect the
 buildbots, and so not noticed/reported due to the binary archive usually
 being available. In particular, the 10.13 buildbot has Xcode 9.4.1 and the
 10.13 SDK, whereas the reporter’s and probably most 10.13 machines instead
 have Xcode 10.1 which does not have the 10.13 SDK. Does the reporter have
 the 10.13 SDK present in /Library/Developer/CommandLineTools/SDKs/ ?

 There are some `ui_debug` commands in the qt5 portfile which might have
 helped with this issue, but they seem to do nothing since they are no
 longer within a port phase block.
